In this embodiment, these are automatically driven by the control device 101 so as to eliminate temperature variations in the test chamber 8 .

That is, in this embodiment, the diffusion means 41 is provided in front of the blower 30 . The diffusion means (hood member) 41 has an opening (substantial opening 76) on its side surface. Therefore, part of the air blown by the air blower 30 is discharged laterally as indicated by the arrow in FIG. flow along 11.

Assuming that the test piece 200 itself does not generate heat, for example, when a high-temperature test is performed, the temperature of the air detected by the temperature sensors 40a, 40b, 40c, and 40d is higher than the temperature of the air blown from the outlet 20. If the temperature is excessively low, the amount of heat in the air adjusted by the air conditioning unit 15 is considered to be insufficient.
In this case, for example, the number of rotations of the blower 30 is increased to increase the amount of air blown out from the outlet 20 .
Alternatively, the temperature of the air adjusted by the air conditioning unit 15 is corrected upward to raise the temperature of the air blown out from the blowout port 20 .

The same is true when a low-temperature test is performed. is increased to increase the amount of air blown out from the outlet 20. - 特許庁
Alternatively, the temperature of the air adjusted by the air conditioning unit 15 is corrected downward to lower the temperature of the air blown out from the blowout port 20 .

When the test piece 200 generates heat and a high temperature test is performed, the temperature of the air detected by the temperature sensors 40a, 40b, 40c, and 40d is higher than the temperature of the air blown out from the outlet 20. In some cases. In this case, the temperature of the air adjusted by the air conditioning section 15 is corrected downward, and the temperature of the air blown out from the outlet 20 is lowered.
